If you rushed home from school for a dose of classic early evening children's TV in the 1980s and 1990s, you'll remember Knightmare.

A stand-out cult classic, Knightmare was known for its blue screen chroma key and virtual reality interactive gameplay.

It was broadcast on CITV from 1987 to 1994 as each week a team of four children tried to traverse a medieval environment and complete a quest.

One child played the role of the sightless dungeoneer and the remaining three acted as their guide from the chamber owned by dungeon master Treguard of Dunshelm (played by the show's presenter Hugo Myatt).
